Deploy the saleor-helm helm chart on Opensshift

Question

Pulumi · Accepted Answer

To deploy the Saleor Helm chart on OpenShift, you'll follow a sequence of steps that leverage Pulumi’s capabilities to interact with Kubernetes, specifically targeting an OpenShift environment. Saleor is an open-source e-commerce storefront, and Helm charts are a way to package applications for Kubernetes.

Firstly, we'll need a Kubernetes cluster running OpenShift where we can deploy our Helm chart. For the purpose of this instruction, I'm assuming that you already have access to an OpenShift cluster and have configured kubectl to interact with it. If you're using OpenShift on a cloud provider like Azure or AWS, you should have the necessary credentials configured in your environment.

Next, you'll need to install Pulumi and set up a Pulumi project. Instructions for installing Pulumi and creating a new project can be found on the Pulumi Getting Started page.

With Pulumi installed and your project initialized, you can start writing TypeScript code using the Pulumi Kubernetes provider to deploy the Saleor Helm chart.

Here is the Pulumi program in TypeScript that will help you deploy the Saleor Helm chart on OpenShift:

import * as k8s from "@pulumi/kubernetes";

// Create an instance of the Kubernetes provider connected to the OpenShift cluster.
const provider = new k8s.Provider("openshift-provider", {
    // Assuming kubeconfig is configured properly in your environment.
    // If needed, you can pass the kubeconfig explicitly.
});

// Deploy the Saleor Helm chart.
const saleorChart = new k8s.helm.v3.Chart("saleor-helm", {
    // Replace with the correct repo and chart name if different.
    repo: "saleor",
    chart: "saleor",
    version: "<SPECIFY_CHART_VERSION>", // Set the desired chart version.
    values: {
        // Define necessary values for your Saleor chart.
        // For example, you might want to set the image tag, resources, or enable ingress.
    },
    // Specify the namespace to deploy to, if not default.
    namespace: "saleor-namespace",
},
{ provider });

// Export the app URL by querying the load balancer status.
export const appUrl = saleorChart.getResourceProperty(
    "v1/Service", "saleor-namespace", "saleor-service", "status"
).apply(status => `http://${status.loadBalancer.ingress[0].ip}/`);

This program does the following:

Imports the Pulumi Kubernetes SDK.
Creates an instance of the Kubernetes provider that targets your OpenShift cluster. It assumes that you have kubectl already configured to communicate with your cluster.
Deploys the "saleor" Helm chart from the specified Helm chart repository. You'll have to specify the correct Helm chart repository (repo) and the chart name (chart). Be sure to set the version you want to use.
Optionally, you can customize the deployment configuration by specifying values in the values property. This would include setting up any specific configurations that Saleor requires, such as persistent volume claims, environment variables, service type, and more.
Attempts to export the application URL based on the service's load balancer status. The specifics of how an application gets exposed can vary based on your OpenShift setup and the Saleor Helm chart itself.

Please make sure to replace <SPECIFY_CHART_VERSION> with the actual version number you want to deploy. In addition, verify the repo, chart, and values based on the specific Saleor chart you are deploying.

To deploy this to your OpenShift cluster, save this code in a file named index.ts within your Pulumi project. Run pulumi up from your command line to have Pulumi apply this deployment to your cluster. This will show you a preview of the actions Pulumi will take and, upon your approval, will execute those actions to deploy Saleor.

Please note that the example above assumes a fairly standard OpenShift environment. Your actual configuration might require additional settings (like setting up kubeconfig) or specific Saleor configurations, which you should include in the values field of the Helm chart instantiation.
